Preferably new, but used is OK if I can get it programmed to use my DESS key. I currently have one good running engine and one that throws immediate check engine and voltage lights on startup, runs rough. When I swap ECUs, the problem moves to the other engine and the engine with the "good" ECU runs fine. Also posted in Utopia sub-Forum.
Please don't recommend Torx Racing, have had a terrible experience with them already.
